Cervicogenic Headaches Flashcards
Where do cervicogenic headaches usually start?
in occipital lobe and radiate unilaterally to head and face
How many pts who suffer from cervicogenic headaches also complain of neck pain associated with their headache?
roughly 70%
What is the anatomical basis for the cervicogenic pain pattern?
Trigeminocervical nucleus (afferents from CB V and Spinal nerves C1-C3 and nuclei of head, throat, and neck afferents)
How does the frequency change between cervicogenic headaches, migraines, and tension-type headaches?
How does the duration change?
cervicogenic are chronic and episodic lasts between an hour and weeks
migraines are usually 1-4 times a month lasts 4-72 hrs.
tension-type can be 1-30 a month and can last days or weeks
What are the possible signs of intracranial pathology for cervicogenic headaches?
- sudden onset of severe headache w/ increasing intensity
- persistently unilateral headaches
- headaches that wake the patient during the night or early morning
- generalized stiff neck or other signs of meningitis
- systemic symptoms (weight loss, fever, and malaise)
- focal neurologic symptoms or signs
Roughly how many patients with headache or neck pain may have cervical artery dissection in progress? How many may be asymptomatic?
1 in 100,000
6% are asymptomatic, 80% head head and neck pain
If a patient says they have pain in their neck and head that they have never felt anything like before what might you be concerned for? What are some major risk factors?
Screen for Atherosclerosis or potential arterial intimal damage (stroke risk)
-hypertension
-hyperlipidemia
-hypercholesteremia
-diabetes
-smoker
-BMI over 30
upper cervical instability
What are the 5 D’s And 3 N’s (red flags) for cervical artery dysfunction?
Dizziness, Drop attacks, diplopia, dysarthria, dysphagia
Ataxia
Nausea
numbness
nystagmus
What is the gold standard for diagnosing cervicogenic headaches? What are some setbacks for this method?
Diagnostic blocks (can abolish migraines for up to 30 days by blocking greater occipital nerve)
Lacks specificity and not feasible in outpatient settings
What percentage of chronic headache patients have cervicogenic headaches?
10-15%
What four things that can cause comparable symptoms of cervicogenic headaches should be screened for in the physical exam?
- Neck movement and/or sustained, awkward head -positioning
- external pressure over the upper cervical or occipital region (active trigger points)
- restriction of ROM and joint mobility in the neck (+cervical flexion-rotation test/abnormal joint mobility testing)
- poor deep cervical endurance (cranial cervical flexion test, neck flexor muscle endurance test)
What constitutes a positive cervical flexion-rotation test?
less than 32 deg. or rotation after flexion
What is the purpose of the cranial cervical flexor test?
What would a normal test result be?
assess deep cervical flexor strength
patient is able to generate 26-30 mmHg pressure for 10 seconds without compensations
What is the purpose of the neck flexor muscle endurance test?
What is a normal test result?
asses deep cervical flexion strength
Over 38 seconds
What 4 examination signs cluster can help rule in/out a diagnosis of cervicogenic headaches compared to migraine or tension type headaches?
- decreased AROM cervical extension
- palpably painful somewhere from OA to C3-C4 joint dysfunctions
- Deep cervical flexor strength impairments w/ cranio-cervical flexion test
